April–June

April 17 – Charles X of France recognizes Haiti, 21 years after it expelled the French following the successful Haitian Revolution, and demands the payment of 150 million gold francs, 30 million of which Haiti must finance through France itself, as down payment.

August 18 – Scottish adventurer Gregor MacGregor issues a £300,000 loan with 2.5% interest through the London bank of Thomas Jenkins & Company for the fictitious Central American republic of Poyais. His actions lead to the Panic of 1825, the first modern stock market crash, in England.
